When configuring hwpmc to use the EXT_SNOOP event, only send a default
cachestate qualifier on the Atom processor. Other Intel processors do not
accept a cachestate qualifier and currently hwpmc will return EINVAL if you
try to use the EXT_SNOOP event on those processors

Update to a config.h created by a file 5.03 configure script. This causes
file.1 to contain the correct version number and SIZEOF_LONG_LONG to be
defined as appropriate, which is crucial for 64-bit big-endian ELF files
to be handled correctly on big-endian systems.

Make it possible to actually use NFSv4 permission bits with acl_set_perm(3)
and acl_delete_perm(3). It went undetected, because neither setfacl(1)
nor Samba use this routines. D'oh.
Fix a bug due to a type conversion from 64 to 32 bits. The side effect of
this type conversion is the high bits which were used to indicate if a
special character was a literal or special were dropped. As a result, all
special character were treated as special, even if they were supposed to
be literals.

Merge improvements from kernel HID parser to the userland usbhid(3)
parser. This merge does not change any API and should not break any
native or thirdparty applications.
Changes include:
* Merge multiple report ID support and other improvements from kernel
HID parser.
* Ignore rid argument in hid_start_parser, parse all the report items since
we now support multiple report ID.
* Skip report ID byte in hid_get_data() and set report ID byte in
hid_set_data(), if report ID is non-zero.
* Reimplement hid_get_report_id: instead get report id from uhid device
(which is always 0), try parsing the report descriptor and return the
first report ID encountered.
MFC r207812
hid_get_data() now expects that the hid data passed in always contains
the report ID byte. Thus we should not skip the the report ID byte in
hid_interrupt(). Also, if HUP_KEYBOARD usage is an array, do not try
to modify the 'data' pointer, instead, increase the hid_item_t field
'pos' by 'report_size' before calling hid_get_data() during each
iteration.

Within libusb 0.1 API, bus number is always faked to 0. Device numbers,
however, are possitive and seem to be reverse sorted in the list.
Conform device numbering and bring a result that is consistent with the
libusb 0.1 API. It is now possible to distinguish a device based on its
(bus, dev) numbers.
Implement the no_user_check option to pam_krb5.
This option is available in the Linux implementation of pam_krb5
and allows to authorize a user not known to the local system.
Ccache is not used as we don't have a secure uid/gid for the cache file.
Usable for authentication of external kerberos users (e.g Active Directory)
via PAM from applications like Cyrus saslauthd, PHP or perl.

Two optimizations to MI strlen(3) inspired by David S. Miller's
blog posting [1].
- Use word-sized test for unaligned pointer before working
the hard way.
Memory page boundary is always integral multiple of a word
alignment boundary. Therefore, if we can access memory
referenced by pointer p, then (p & ~word mask) must be also
accessible.
- Better utilization of multi-issue processor's ability of
concurrency.
The previous implementation utilized a formular that must be
executed sequentially. However, the ~, & and - operations can
actually be caculated at the same time when the operand were
different and unrelated.
The original Hacker's Delight formular also offered consistent
performance regardless whether the input would contain
characters with their highest-bit set, as it catches real
nul characters only.
These two optimizations has shown further improvements over the
previous implementation on microbenchmarks on i386 and amd64 CPU
including Pentium 4, Core Duo 2 and i7.

* un-document 'struct sigaltstack' tag for stack_t as this is BSD-specific;
this doesn't seem useful enough to document as such
* alternate stacks are per thread, not per process
* update error codes to what the kernel does and POSIX requires
POSIX permits but does not require checking access on the current and parent
directories.
Because various programs do not like it if getcwd(3) fails, it seems best
to avoid checking access as much as possible. There are various reports in
GNATS about this (search for getcwd).
Our getcwd(3) implementation first queries the kernel for the pathname
directly, which does not check any permissions but sometimes fails, and then
falls back to reading all parent directories for the names.

Slightly modernize realpath(3).
SUSv4 requires that implementation returns EINVAL if supplied path is NULL,
and ENOENT if path is empty string [1].

While SPARC V9 allows tininess to be detected either before or after
rounding (impl. dep. #55), the SPARC JPS1 responsible for SPARC64 and
UltraSPARC processors defines that in all cases tininess is detected
before rounding therefore rounding up to the smallest normalized number
should set the underflow flag. This change is needed for using SoftFloat
on sparc64 for reference purposes.

Additionally, because of sysctl(3) use (which is generally good), behaviour
for crash dumps differs slightly from behaviour for live kernels and this
will probably never be fixed entirely, so weaken that claim.

Still reference struct __sigaction with clarification when this form

domain clock, 8 programmable PMC.
- Westmere based CPU (Xeon 5600, Corei7 980X) support.
- New man pages with events list for core and uncore.
- Updated Corei7 events with Intel 253669-033US December 2009 doc.
There is some removed events in the documentation, they have been
kept in the code but documented in the man page as obsolete.
- Offcore response events can be setup with rsp token.

Use panic() (which the environment is required to provide to libstand) to

invocation also did not match the semantics of the exit() routine that
current boot environments happen to require.

- If an infinite result is rounded down, the result should have an
exponent 1 less than the value for infinity.

Use thr_once() with once_t controls to initialize various thread_key_t
objects used to provide per-thread storage in the RPC code. Almost all
of these used double-checking with a dedicated mutex (tsd_lock) to do this
before. However, that is not always safe with more relaxed memory orders.
There were also other bugs, such as one in __rpc_createrr() that caused a
new key to be allocated each time __rpc_createrr() was invoked.
- The OPSZ macro actually only does the right thing for int32 and int64
operands but not for double and extended double ones. Instead of trying
to fix the macro just nuke it and unroll the loops in the correct way
though as extended double operands turn out to be the only special case.
- For FxTO{s,d,q} the source operand is int64 so rs2 has to be re-decoded
after setting type accordingly as it's generally decoded using the low
2 bits as the type, which are 0 for these three instructions.
- Similarly, in case of F{s,d,q}TOx the target is int64 so rd has to be
re-decoded using not only the operand mask appropriate for int64 but
also the correct register number encoding.
- Use const where appropriate.
- Wrap long lines.
